WILLIAM T. LINN, 0F ARKANSAS CITY, WTSAQ.

Laaaasa Application filed July 31, 1914-.

To all whom it may concern:

Be it known that 1, WILLIAM T. LINN, a citizen of the United States, residing at Arkansas City, in the county of Cowley and State of Kansas, have invented certain new and useful limprovements in (lrainQDoors; and 1 do hereby declare the follo wmg to be a full, clear, and exact description of the invention, such as will enable others sk1lled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in grain doors, and has for its principal object to provide a grain door which is particularly adapted for use on box cars of the ordinary type.

Another object of the invention is to proride a grain door having a removable lower panel to permit the contents of the car to be easily and quickly disposedof.

A further object of the invention is to provide a simple and etlicient lock for the door which will prevent unauthorized persons from entering the car and also elim nate any danger of the door becoming accidentally opened.

A still further object of the invention 15 to provide a means for supporting the sevcral panels making up the door in such a position as to be out of the way when they are not in use.

Still another object of the invention is to provide guides for the panels which may be swung upwardly so that the car may be used in the ordinary manner and any danger of injuring the guides eliminated.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which,

Figure 1 is a side View in elevation of a car having a grain door secured thereto constructed in accordance with this invention,

Fig. 2 is a longitudinal sectional view of the car showing the interior construction thereof,

Fig. 3 is a transverse sectional view taken on line 33 of Fig. 1,

Fig. 4 is a longitudinal sectional view showing the door removed and the guides swung upwardly,

Fig. 6 is a detail perspective view of the bottom panel of the car door.

Referring now to the drawings by charac ters of reference, the numeral 1 designates as an entirety the box car of the ordinary construction comprising the frame 2 which supports the bottom 3. Secured to the bottom are the side walls 4. and 5 having the usual door openings formed therein. These door openings are provided with the ordinary door posts 6 as clearly shown in Fig. i. The usual roof 7 is provided and the door posts are connected at their upper ends with the roof supports 8 which are arranged to form supports for the several panels of the door as will be more fully hereinafter described.

Pivotally secured as at 9 near the upper ends of the door posts are provided the guides designated generally by the numeral 10. These guides comprise the flanges 11 which are bent angularly along one of their edges as at 12. The angular extensions are again bent as shown at 13 and extend substantially parallel with the members 11 hereinbefore referred to. These flanges 11 are provided near each end with the apertures 14, and have formed centrally thereof the slots 15, the use of which will appear as the description proceeds. Secured to the door post intermediate its ends and designated by the numeral 17 is a suitable bolt or lag screw which is arranged to enter the slot 15 and materially assist in holding the guide in place. The aperture 14 in the lower end of the flange 11 is arranged to receive a suitable lag screw which is arranged to enter a nut whichis countersunk in the door post 6 at 18 to firmly hold the guide in place. This lag screw is also arranged to enter a countersunk nut carried in the beam 19 which extends longitudinally of the car to support the guides in their raised position as illustrated in Fig. 4.

Cooperating with the guides 10 hereinbe fore described, are the segmental guides 20 which are secured to the roof supports 8 as at 21. These segmental guides are arranged to hold the topmost panel of the door in proper position to prevent the same from falling inwardly.

Secured to the roof supports 8 are the angle members 22 having the supporting flange 23 upon which the panels of the door rest when not in use. This supporting flange 23 is placed beneath the flange of the movement of the car.

doe; aereby. preventing the grain caric ricd v 1.". the car from escaping. Each of these panels is provided with such a flange with the exception of the bottom panel which is designated generally by the numeral 26, and which comprises. the main body portion 27 and the hinged wing 28. llhis body portion 27 and hinged wing are secured to eachother by means of the hinge 29 whichis preferably countersunk to form a relatively smooth surface to A prevent the grain from lodging on any shoulders formed thereby. Secured to the opposite slde of the element 27 is a suitable bar 30 provided with the prongs 31 which are arranged to form a reinforcing means for the member 27. lhis member 30 terminates at the end opposite the pronged end inthe reduced extension 32 having the slot 33 formed therein. This slot 33 is arranged to receive the staple 34 carried bythe wing 28 and thereby form suitable pin 35 is arranged to extend a hasp. which will eflectively lock the wing and body portion 27 against movement. A;

through the staple to lock the whole and said pin is provided near its reduced end with a suitable slot through which the car seal may be passed.

llt will be apparent from the that in use the bottom panel 26 is position betweenthe guides 10 and the remaining panels piled thereon as shown in Figs. 1, 2, and 3. The car is then loaded with the material which is to be shipped, and after reaching its destination the seal which is placed in the lowermost panel is broken, thus permitting the pin to be withdrawh and allowing the panel to swing outwardly on its hinge 28 so that the same may be easily and quickly removed and the grain foregoing contained within the car permitted'to flow through the opening thus formed. After the car has been entirely emptied the panel 24 may he slid upwardly across the segmental guide member 20 until they engage the angle member 22 and rest on the flange 23 as shown in Fig l. In this position it will be apparent that Copies of. this patent may he obtained for five cents each, by addressing the placed in.

the several panels will r antenna 7 they will be easily and quickly placed in position and the car converted into a grain car on short notice. lit will be further ap parent that with the use of a door of this character, a much tighter grain door is provided and any danger of leakage of grain is eliminated.

While in the foregoing there has. been shown and described the preferred embodi ment of this invention, it is to be understood that such changes may be made in the combination and-arrangement of parts as will fall within the spirit and scope of the invention as defined in the appended claim. Having thus described my invention l:

j claim The combination with a car having a door opening, of vertical guides pivoted at their upper ends to the car at opposite sides of the door opening at the upper portion thereof said guides being arranged to swing upwardly in, opposite directions longitudinally of the car andaway from the door opening to arrange them at the top of the car out of the way, means located at the lower ends of the guides for securing them in their vertical position and also'in their position at the top of the car, spaced transversely disposed supporting members secured to the top of the car and forming a horizontal track, a grain door operating in the vertical guides, 'and short segmental guides fixed to the car at the top thereof above the vertical'guides and extending above the plane of the track formed by the transverse supporting members. for guiding v the grain door onto the letter.

-In testimony whereof I aflix my signature in presence of two witnesses.
